Is it OK to keep my phone plugged in?

When I sit at my desk at work, I tend to keep my phone plugged into the charger. Then when I go to bed, I put on the Do Not Disturb and plug in the phone. Do you think this will cause damage to the battery? Would this make it die faster or does the charger shut off when the batter reaches 100%?
 
I plug mine in whenever I'm not using it. I try to not let it get below 50%. My wife let's hers die regularly. After 2 years my battery will still last a full day with moderate use while hers will die in just a few hours with light use.

I would say it's fine to leave it plugged in. Much better than letting it die all the time.
 
ive heard that these days it is best to charge at around the 40% left mark - bad to let it die completely
 
The age ol question... The answer it YES.. its fine to keep ur phone plugged in at all times if u like.. These new phones have lithium ion batteries not the old batteries from ten yrs ago which were I think Nickle. So keep it plugged in
 
It turns out that this can be a rather polarizing question. My M8, SGS5, Nexus 5 and LG G3 have no specifics regarding charging.

Conversely my Note 3 puts up a nice message in the notification area once the battery is fully charged asking me to remove the charger.

I follow that and now many months after release day when I bought it, I'm enjoying exceptional battery life.
 
I read sometime back ,in regards iphone that you should never let the battery charge over 90% full to save the full lifespan of the battery. Important for an iphone, because it is difficult to change. I have often wondered if charging at 0.5V is better for the battery lifespan than charging at 1.5V

I've been using the charger that came with my son's Nexus 7 for my EVO LTE for over a year, I think it's 1.5. The battery life on it is far better than on my wife's S3.

Because Samsung let out a batch of bad phones with faulty chargers resulting in fires, they started adding that nag message.

And then they insisted that the victims sign gag orders to not discuss it in order to get phones replaced.

None of that had to with design.



Nothing bad happens with the phone left on the charger.

Not dropping power below 40% is also nonsense.


It's not magic, it's about chemistry and physical structure.

Lower the charge level, rapidly deplete what's left and the heat will spike high and hard. If that happens, then the metal structures that make up part of the battery will deform. If that happens, lifetime goes down along with everything else.

Don't run your phone hot for prolonged periods at any charge level.

Don't force it to stay on when it tells you it's time to shut down.

Don't worry about leaving your phone on the charger, it will get disconnected and stay that way until the charge drops to around 96% and then connect to start charging again.

"Oh no, I left my phone on the charger and now it drops 5% in 5 minutes!"

No.

You take the phone off the charger and it takes 5 minutes or so to see the actual charge level.

Just like your laptop.

Same behavior, same reason, same technology.

They charge at 5V, you mean 0.5 to 1.5 amperes.

Voltage is forced.

Current, measured in A or amps, is drawn by the device. You can put an iPod on a 2 A charger and it will only draw 0.5 A. No difference in anything if you change chargers, it won't matter.

I don't know what myths are being sold to the iPhone crowd but 90% is just that here - another myth.
